Students also learned:
Geotechnical engineers use their engineering knowledge and knowledge of the layers ofearth to help evaluatelandscapes and decide the best sites on which to build structures.- They identified that many factors affect whether a site is a good choice on which to build
a structure, including type of soil, probability of erosion, and the needs and wants of citizens . - We discussed and collaborated on the site of the
structure and the importance of longevity. - We identified that the Engineering Design Process is a tool that can be used to help solve
problems .
The Tie-In Science Content
Landforms change over time and we need to take that into consideration when building abridge .- Erosion is the wearing away of earth materials by water, wind, or ice.
Student Misconceptions:
- Technology is only things that move.
- Technology is only computers.
- Technology is only things that use electricity.
- We had some outstanding collaboration on these misconceptions.
Student Insights:
- They came up with the theory that anything that people design to solve a problem is
technology . - Technology doesn’t always use electricity.
- People design technology.
- Technology can be used and made of lots of different materials.
- An engineer’s job is to design technology.
